Logwatch Disk Space Usage is Wrong/Stale@Tim, do you want to add your comment as an answer so I can accept it (it was the key piece I didn't think about doing). I'll put more information in for people who are curious in my own answer. :-)

Run more than one HypervisorI think you would be better off asking for money for an extra server to run ESXi on. Before we were really on board with a bare metal hypervisors we ran a couple servers on VMware Server and it was a nightmare. I'm betting your time is worth more than a new server. :-)

OS X Computer names with (#) randomly added at the end@Robert, do you want to add that as an answer so I can accept it? Do you know if the user of the computer would get an error message when this happens? The network these computers are plugged into has had multiple problems so I can see it happening. :-)

Strange VMWare networking issueHave you tried rebooting the CAS server while it's on the second host? VMware sends a reverse ARP when it vmotions a VM and it's possible that your switch thinks it's still on the first host.

How to deploy vmview from a single esx serverHypervisor (VMware product) is a type 1 hypervisor (generic term) so it runs on the "bare metal" in lieu of an OS so if you already have an OS installed it will have to be reinstalled or converted to a VM. It's a good use of a large VM hosts because it can better manage the memory, network access, and CPU and you don't have to worry about the Host OS crashing. VMware Player is used for running VMs inside another OS and if I remember correctly, (I haven't used it) it doesn't allow you to create a new VM or edit them once they are created.

MySQL Replication, Master vs Slave commitsYou can use mysqldump to make the backups and then restore them with the mysql command. I would actually recommend setting up a dev environment for each developer on their local computer and then have a shared test/QA environment. That way they can mess up their own data without affecting everyone else. :-)
